The Carbon Express Maxima XL 23 is a 23-class diameter arrow built for competitive 3D shooters who prioritize consistent, repeatable flight and scoring advantage. Its larger diameter supports line-cutting potential, while Tri-Spine Technology stabilizes the arrow at launch for predictable tracking downrange. 360 degree spine consistency promotes uniform shaft behavior for reliable tuning and match-to-match accuracy. Straightness is rated to +/- 0.025 inches max with a +/- 1.0 grains weight tolerance, and it includes 12 Bulldog nock collars.
